TRANSPLIT DEMOUNTAIBLE RIM.

mountable rims which are adapted to carry pneumatic tires in inflatedcondition.

In dealing with demountable rims, it is necessary that the same shall beformed for easy assembl with the tire and shall be easy to detac In thecase of rims of the Y clencher. type, it is desirable, and in the caseof rims of the strainght-side it is essential, that the rims, ii of theintegrally 20' split I means transversely cut across to form flangedform; shall be transplit. By tranrim ends which may be helically searated. When a rim has been transplit it comes necessary to providemeans for connecting the ends of the rim at times when it is on thewheel, and it is also desirable that the rim-end connecting fmcans shallbe adapted to always hold the rim ends in alinement andprevent theirdis-alinement in any direction.

The object of my invention is to simplify the construction of transplitdemountable rims, and to improve the action thereof.

The general nature and principles of my invention, and also the detailsof the best embodiment thereof that I have thus far devised, will bereadily understood on reference to the drawings which form part of thisspecification, and are particularly pointed tutc an effective run endconnector, by which the rim ends are positively and non-adjust out inthe appended claims.

Referring to the drawings :-Figure 1 is an outer side elevation of afully equipped motor vehicle embodying my invention Fig. 2 is anenlarged side view of a portion of the rim and wheel, parts thereofbeing in section on substantially the middle plane of the w eel ;Fig. 3is asection on the curved line X-X of Fig. 2, the same showing the innerperiphery of the rim at the split;-Fig. 4 is a cross-section 'on theline Y-Y of Fig. 2;-and Fig. 5 is a modified form of the locking device.

the felly-band or fixed rim ;5 the demountable rim;6 several clampingdevices by whlch the same is ,secured' on the fixed rim ;and, 7 thepneumatic tire.

The demountable rim 'is rovided with integral flanges 5"; and, in or erthat it may be put into and taken out of the tire, it is transplit. Inthe present instance I cut the rim transversely across upon the majordiagonal line, A, and upon a minor reversely diagonal line, B. In thismanner I form the rim ends, 5 and 5. A split much the same is generallydescribed and claimed in my pending application Serial No. 86,598. Thusformed, the rim ends are self-alining; that is, they are adapted towithstand the compressive force of an inflated pneumatic tire, withoutdislodgment. In the rim-end, 5, I rovide a hole, 8, and in this I placea be low rivet, 9, having a large head, 10. In forming the hole, 8, Ipress down the metal from the body of the rim, making a sleeve or boss,8, which is integral with the rim. .As shown in Fi 4, the head, 10 ofthe rivet is larger than t 'e boss, 8, and serves to confine on thelatter a latch-plate, 11. In the felly band, 4, I form a hole, 12, whichreceivesthe head, 10, of the. rivet, 9. In this manner one end of therim is anchored to the felly band, when the rim is placedthereon. In theopposite end, 5", of the rim, I form another hole and integral boss, 13,and

- therein secure a solid rivet, 14, having a large head, -15. This head,like the other, is accommodated in a hole, 16, in the folly band. Thusthe other end of the rim is anchored to the folly band. The two studs orrivets together with the intervening portion of the felly band, or fixedrim, constiably, but detachably, connected, when on the wheel. swiveledon the boss, 8. Its free end, 8, is formed to swing beneath the head,15, of the rivet or stud, 14. When in that position the plate extendsacross the split, A, and being firmly held between the inner peripheryof the rim and the heads of the two rivets or studs, it serves toprevent the radial disalinement of the rim ends. When desired, the endof the latch may be formed as a hook, 8", to further engage and co-actwith the stud, 1%, as shown in Fig. 5.

The plate, 11, obviously, is

This simple device adds little to the cost of the demountable rim, andadmirably serves the desired purposes.

- I desire that it be understood that the described latch may be usedwith rims which are transplit upon other than diagonal lines, thoughthe, construction herein disclosed is much to be preferred. It isobvious that a hollow rivet, 9, is not required, unless it is desired toaccommodate the valve stem,

7, of the tire in the manner shown in these drawings.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A transplit demountable rim having a struck-downboss on one end, in combination with a latch plate swiveled on said bossand a headed rivet within said boss, and holding said plate on the rim.

2. A- demountable tire-carrying rim, the tire embracing part being ofone piece and being diagonally split across at one point in i on theother. end of the rim to prevent v radial disalinement of the rim ends,and the pivoted end of said latch containing a valve stem hole.

combination with two driving studs, one on each of the ends of saidsingle tire-embracing part, one of said studs being hollow and 3. Atransplit demountable rim of which the tire-embracing part is in onepiece, in-

thus presenting a valve stem hole and a latch plate pivoted on saidhollow stud and formed to interlock with the other stud 011 the otherend of the rim.

In testimony whereof, I have hereunto set my hand this 9th day ofAugust, 1916.
